UPDATE: CBS' SUPERGIRL Has A Superman, & Will Go Head-To-Head Against GOTHAM

Update May 13: In the annual TV upfronts, CBS has reportedly announced their plans for the upcoming Supergirl series. The one-hour show will air Mondays at 8pm EST beginning in November, which is coincidentally putting it head-to-head against Gotham on Fox unless that network changes its schedule.

CBS also revealed the official plot synopsis of the show, which seemingly confirms that Superman exists and is public knowledge in the show's continuity while the titular star is looking to keep her identity secret.

SUPERGIRL is an action-adventure drama based on the DC Comics character Kara Zor-El (Melissa Benoist), Superman’s (Kal-El) cousin who, after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be. Twelve-year-old Kara escaped the doomed planet Krypton with her parents’ help at the same time as the infant Kal-El. Protected and raised on Earth by her foster family, the Danvers, Kara grew up in the shadow of her foster sister, Alex (Chyler Leigh), and learned to conceal the phenomenal powers she shares with her famous cousin in order to keep her identity a secret. Years later at 24, Kara lives in National City assisting media mogul and fierce taskmaster Cat Grant (Golden Globe Award winner Calista Flockhart), who just hired the Daily Planet’s former photographer, James Olsen (Mehcad Brooks), as her new art director. However, Kara’s days of keeping her talents a secret are over when Hank Henshaw (David Harewood), head of a super-secret agency where her sister also works, enlists her to help them protect the citizens of National City from sinister threats. Though Kara will need to find a way to manage her newfound empowerment with her very human relationships, her heart soars as she takes to the skies as Supergirl to fight crime. Greg Berlanti (“The Flash,” “Arrow”), Ali Adler, Sarah Schecter and Andrew Kreisberg are executive producers for Berlanti Productions in association with Warner Bros. Television. The pilot was directed by Glen Winter (“Arrow”).

Update May 6: Deadline is now reporting that Supergirl has officially been picked up for series with an early order for season one coming just before CBS begins its upfronts, when pilots are shown and programs are given series orders.

Original Story: She's a bird, she's a plane, she could be going to series.

According to Variety, CBS's Supergirl pilot has a "good chance" to be picked up for series.

In a report that details various networks and their upcoming shows, Variety says that Supergirl will stick around at CBS, despite some rumors that it may move to the CW. Supergirl will remain at CBS to take advantage of a bigger budget, and a slightly older audience than the CW.

Further, it clarified that a first look trailer for the show would be seen on May 14, at CBS's "upfronts," a showcase for upcoming projects.

The Greg Berlanti produced Supergirl stars Melissa Benoist in the title role, and if greenlight could debut this fall on CBS.
